The FreeBSD mfi will not support that card.  The LSI mfi will, but they
aren't done with it as far as I know (spoke with their driver team a few
weeks ago)

The slightly riskier option is to flash the card with IR firmware for a
9211, the MegaRAID component of that card is purely software and the
underlying hardware is supported by mps.  Of course a firmware flash
gone bad will turn it into an expensive chunk of fiberglass, but if you
google around you'll find people who have done so successfully.
